To all whom it may oooce m Be it known that I, Eowgieo L. iiicrieoio'r,

e citizen of the Unit-ed Stotes, residing at Pittshiirgh in the county oi Allegheny eiirl Ser ei Pennsylvania, hove iiirei'iterl it new end usefui improvement in tlooei'ete-lliloorh WtltY IiiBlH'fOIClIl Fabric, of Whieh the tot lowing is a full, clear, and erect description, reference being" had to the accompanying drawings, forming part oi this speeifiosrtieii in "which: 3

Figure 1 is a, plan View iilostretihg the manner of laying my improved, reinforcing fabric, and

My invention relates to fehrio for reiiiforoingeonerete roadways anti else to conoi'ete I'OZtClWELES having such fabric eiiiherlrleri therein.

@RB ohject oi the invention it to provide a, fehrio of this character which will have greater Weight of metal running i312t11S- rersely of the roadway than longituc strength is required.

of fabric which have the same wei ht of metal throughout their width, and overla pin such strips of fabric along the ,mid e of t e roadway.

"" 11: :As shown in Fig. 1, the fabric can be formed into a roll b rolling in a direction at right angles to t e len h of the reinforcing elements, thus ma 'ng it unneces-' sa to bend such, elements in rolling. In la mg the fabric, the roll or spindle upon comprising orc1 races coanparativel heavy transverse 'rein elements a apted to be laid transverse y of the roadway and comparatively light longitudinal flexible tie wires, substantially as described.

2. A concrete roadwa reinforcing fabric adapted to be laid lengthwise longitudinally of a roadway and having a considerably greater cross-sectional area along a longitudinal section than along a transverse section, substantially as described. 3. A concrete roadway having reinforcing fabric embedded therein, said fabric bein laid len hwise longitudinall of the ma way an having com arative y heavy transverse reinforcin e ements and comparatively light longitudinal tie wires, substantially as described. 1

4. A concrete roadway having reinforcing fabric embedded therein. said fabric bein laid len hwise longitudinal] of. the way an having com araJve y heavy trans verse reinforcing e ements and comparaw ichit is wound can be placed transverselyf' tivelylslight longitudinal tle wires, said roadof the roadway with its ends resting upon the forms 8, and the fabric can thenbe unwound in the direction of the length of the roadway. This enablesaconsiderable length of fabric to be laid in continuous stretch without cuttin and greatly reduces the number of over aps required.

The advantages of my invention will be readily apparent from the foregoing, since it provides a fabric for the purpose described which can be manufactured and laid much more conveniently and economically than was ossible with fabrics heretofore in use. I c aim: 1. A concrete roadway reinforcing fabric,

way aving a greater number of reinforcing elements a ong its middle portion than at its. side portions, substantial] as described.

5. A concrete roadway aving reinforcing fabric embedded therein having transverse reinforcin elements and longitudinal tie wires, sai roadway having the reinforcing elements extending from each side of the roadway past the center thereof so as to form a considerable over-lap along the middle portion of the roadway, substantially as described.

In testimony whereof I havehereunto set m hand.
